As the designs of the two great European powers were craftily concealed through their evasive system of diplomacy, it has frequently been a subject of debate as to whether they meant to take the part of the Confederacy for the purpose of dissolving the Union. It is necessary, therefore, to produce some tangible evidence of the intentions of these foreign potentates in the hour of our country’s greatest peril. The Confederate records purchased by the Government some years ago throw a ghastly light on this subject, and gravely warn us of the Scriptural injunction, to put no trust in kings and rulers. The correspondence between the officials of the Confederacy and the Confederate Commissioners, Slidell and Mason, at Paris and London, prove to a demonstration that the ruler of France and the rulers of Great Britain were making preparations on a large scale to take charge of this country as soon as the Union, through their diplomatic aid, should be dissolved. Letters from other representatives of the Confederates of Europe go to corroborate this view of the matter. The correspondence between Dudley, Post, Mann and Lamar, who were commissioners in various parts of Europe, and Judah P. Benjamin, the Confederate Secretary of State, is conclusive on the subject of European armed intervention, which has hitherto formed a topic of dispute in the historic circles of the Civil War. The correspondence of Slidell, who was on familiar relations with the Emperor of the French, gives the inside history of the intrigues of that potentate in such clear terms, that there can be no doubt of his intentions towards this country. Had it not been for the superior vigilance of Mr. Dayton, the United States Minister at Paris, several privateers would have been launched from French ports to prey upon the commerce of the United States, and to do similar work to that for which the Alabama was fitted out. It would seem from the correspondence that the managers of the affairs of Great Britain were not so anxious to encourage the South as Napoleon was; at least they succeeded in concealing their purpose better. The practical diplomacy of England in this affair was superior to that of France, though the latter has still held the palm for possessing better diplomatic plotters, who are supposed to have no superiors outside the royal associations of the reigning power of Russia. There is no doubt, however, that Napoleon was anxious to take positive steps to recognize the South, while professing the most friendly feelings in favor of the North, but he was afraid to act except in unison with Great Britain, and he failed to bring her to time until the favorable moment for the execution of his plans had passed.
